8106

Category: Alarm

Cause

Condition: the position detector generates an abnormal pulse signal. Causes:

1. Position detector wiring incorrect.
2. Position detector connector loose.
3. Poor position detector wiring connection.
4. Interference causes encoder communication disconnection.
5. Position detector damaged.

Corrective action

1. Verify that the wiring matches the recommended circuit in the manual and wire it correctly.
2. Inspect CN2 on the drive and the position detector connector for looseness, and reinstall them.
3. Check the detector, drive CN2, and both motor ends for poor wiring connections or broken/damaged cables; replace connectors and cables if necessary.
4. Monitor the encoder communication error rate P0.002 = -80. If the value keeps accumulating, interference is present; check the following: (a) Verify that the motor grounding terminal is properly grounded; connect the power cable grounding conductor (yellow-green) to the drive heatsink (Heat Sink). (b) Verify that the encoder signal cable is normal and keep it separate from power supply or high-current wiring to prevent interference. (c) Check whether the position detector cable has shielding.
5. If the alarm persists after all the above checks, replace the motor. Clear by powering on again.
